Our users can have a P.O. Box as their address (or a false address), whatever they want as their 'real name', and can pay for their accounts by mailing in cash. All they need to do is be close to a phone that isn't theirs for an hour or so.
The can put in a phone# when they set up, then call in from that phone (even if it isn't their own) and have one of us call them back with a few minutes...all set.
Of course, you can also do this with CompuServe or any service that uses phone verification. I opened my CompuServe account in my True Name but with the phone number of one of my mail receiving services. They wanted a similar callback scheme as above. I went to my mail receiving service, called the CIS 800 number and they called me right back. I was friendly with my mail services so had no trouble. DCF
